Manufacturer Specified Performance Parameters
Vetted Performance Status
- Out of the 300 households studied, 200 households (66%) continuously boiled the water using the Jiko Kenya stove every day, which exceeded the initial target of 60%.
- 95% of households reported an 80% reduction in the incidence of waterborne diseases, compared to the period before they used the stove.
- In Kitui County, the percentage of children who missed school as a result of water-related illnesses was reduced by more than 80%, due to the project.
The safety concerns associated with the usage of wood-burning cookstoves are primarily related with carbon dioxide, carbon monoxide and sulfur dioxide emissions. Another significant safety concern is domestic accidents such as accidental burning or spill-overs.
